Be it known that I, GEORGE W. KELLOGG a resident of Rochester, inthe-county of Monroe and State .of New York, have in vented certainments in Detach Lew and useful Improve- 2. le Pumps; and I do herebydeclare the follovt'in' to be a full, clear, and

0 the invention, such" as will enable otheri skilled in the art to whichit ertains to male and use the same.

he' inventiongrelates to power' driven r m ating pne'imatic tires, butadapted e i also for otherus p The objjct of tie invention is to providesim le an efficient means whereby a pump. wit its .gearing, ifndsuitable; for'such use,

y a lily setured temporarily and at will to an exterior drivingpinionsecured to a suitable powerjdriven shaft in conven 'ient situationfor} connecting the pump theretoand disconntcting it therefrom.

The invention corsists in theconstruction here'nafter'described andparticularly point ed out. v

' In the accompanyirlg drawing whichillustrates the invention and formspart of the specification,Figures 1 and 2 are respect1vely. an elevationand an end View of'the ing mechanism of the pump, an an exten-' slonpart 2 adapted tofit over a pinion 3,

the latter not forming a permanent part of' the pum but being secured toany suitable driven s aft- 4, which may be, for example, an engine ormotor drivenshaft on an automobile. Pinion 3 is preferably made in twoparts, with securing means for easily connecting the pinign to itsshaft. The hub 5 of this pinion is large, and projects on both sides ofthe gear teeth, as shown most clearly in Fig. 4, w ich shows the lowerhalf of the pinion and. 1 hub. Part 2 of the body is adapted to fit ovrpinion 3, and-t0 partly enclrcle hub 5on both sides of the circle ofteeth. I I 1 'Pivoted to-bodylat 6 is a strong movable jaw also adaptedto fit over and partly surround the pinion if and its hub. Both part 2and'jaw 7 have agroove 8 loosely receiving 7 nn racnannu 954',se4./

Having thus descrlbed the invention what I claim is, 1. In a device ofthe character erating'gearing-carried by said body, said the same fromc.

The pump can be attached to pinion 3, or I detached-therefrom in amoment, and in such eflicient manner that the pmion, and wheel 13 areheld in cooperating relation as though they were both (and not wheel 13only) permanent parts of the pump mechanism.

The invention is not confined to all the details of construction setforth as they may be varied within the principle of the in;-

/ described, a' supporting body, a pump comprising opbody having anextension, a movable pivoted part cooperatin with 'the extension, saidextension and sai -inovablepart being adapted to rotatably hold thepumpgearing in cooperating relation with an exteriordriving pinion. J r
